My guess is that class rank is important but not the end all be all. My DD was accepted last year as an incoming Freshman and had a single digit class rank, but was also well rounded. I assume they look at the whole package to find kids that are well rounded and show a drive in STEM. I also assume that they are always looking to bring in kids from schools or areas that haven't had a ton of exposure to USNA. Hence, you rarely hear of kids getting accepted more than once...which selfishly is a shame bc she really wants to go again.
